----------------------------------------------

American Gem Trade Association Gemstone Enhancement Codes

Enhancement: Any treatment process other than cutting and polishing that improves the appearance (color/clarity/phenomena), durability, or availability of a gemstone.

ASBL:
Products made of multiple layers or combinations of manufactured and/or natural material fused, bonded or otherwise joined together to
increase stability and/or imitate the appearance of a natural gemstone, create a unique design or generate unusual color combinations.
NOTE: “ASBL” coded stones require special care! Avoid household chemicals, cosmetics, abrasives, and sudden shocks.

Since this cabochon was thin, I added a thin layer of J-B Weld steel epoxy bonded to the back of the natural stone for added strength.
